7. When do I receive a “Notice of Value”?

The County Assessor mails a “Notice of Value” to property owners every year. The notice will indicate the assessed valuation of Market Land and Building, New Construction, Crop, etc., Current Use Land, and Senior Frozen Value, if applicable.

8. What if I did not get a “Notice of Value”?

If you did not receive a “Notice of Value” at least 15 calendar days prior to the deadline for filing the petition for the current assessment year, and your valuation changed, contact the Clerk of the Board of Equalization. (WAC 45814.127)


Please note: The Assessor is required to send the notice to the owner of record whose name and address appears on the assessment rolls. The property owner is responsible for notifying the Assessor of any address change and/or for requesting copies of notices for a mortgage company or lending company.

9. When will I have a hearing?

The Clerk of the Board of Equalization will notify you of the location, date, and time of your scheduled hearing three weeks in advance of the hearing date.

10. What can I expect at the hearing?

You and the Assessor’s representative will have the opportunity to give oral testimony and written evidence to support the assessed valuation. You may cross examine each other and rebut evidence. The hearing is an informal review designed to allow property owners to represent themselves without an attorney. Keep in mind, the Assessor is by law, presumed to be correct. The burden of proof is on you, the owner, to show that the assessed value is not accurate. You must present clear, cogent, and convincing evidence to support your estimate of market value.

You will usually receive a written decision from the Board of Equalization. The Board can either raise, lower or sustain the Department of Assessments’ valuation.

You may appeal the Yakima County Board of Equalization’s decision to the Washington State Board of Tax Appeals.

The local Board of Equalization has a supply of state appeal forms for your convenience.

13. Should I wait until after my hearing to pay my property taxes?

No! Pay your property taxes when they are due. After your hearing, when the Board of Equalization has made their decision, the County Treasurer will notify you of any adjustment to your taxes.
